To allwhom iii may concern:

Be it known that I, I-IosnA II. Srnnirr, a

citizen of the United States of America, and

a resident of Overlanchinthe county of'St.

Louis and State of Missouri, have invented paper-feed guides forplaten-presses, one of the objects being-to produce a simple andinexpensive device of" this kind adapted to be readily secured to atympanto serve as a stop, or gage, for the sheets of paper delivered tothe 'tympan.

A further object is to produce-a simple.

feed guidehavingan adjustable tongue extending from its head, orabutment, so as to limit the upward motion of the edge of the paperengaging the abutment, the. adjustable tongue being secured by the meanswhereby the device is attached to the tymaan. I

Fig. XI is .a front GlGVttlOnOftlle grip- FigfX is a side elevation ofthe gripping A designates a tympan sheetadapted to be secured to theplatenB (Fig. III) by means of a tympan-drawer Gshown in Fig. I. A-sheet of paper D, mounted onthe tympan, is adapted to engage guides -Grwhich are secured to the tympan to deter: mine the location of the paperto be printed. Each guide G" includes aframe shown most clearly by Fig.VII and including a back flange 1, side arms 2 formed integral with andextending'forwardly from the ends of said back flange, and a pair ofprongs 3 formed integral with and extending forwardly from thefloweredge ofthe back flange, Allof these'parts maybefmade of a singlesheet.of metal, as shown by 'Fig. VII. For a purpose to=be hereafterpointedout, each side arm 2 is provided with a front perforation.atnearfitsfront end and a rear perforation 5-nearits rear end. A gripping lever Eis located between the. side arms-12. Figs'IX, X and XI are detail viewsof this lever. f It is sheet of metal depressed'fat the middle as shownbyFigs III, Vand X, and having a downturnedabutment fiange 6 at .itsfront end and curved pivot-forming extensions-7 near its rear'enchsaidextensions beingf located in the rear perforations 5 in the side arms,so as to pivotally connect the grippreferably -made of a single pinglever to said side arms. Each extenslon 71s preferably curved to conformto the wall of a perforation .5, as shown in F 1g. V.

F designates a locking lever VIII) comprising a single sheet ofinetallocated between the sidearms 2 (F igQII) and hav-.. ing pivot-formingextensions 8 projecting through, the frontperforations 4: in said sidearms. These sheet metal extensions 8 are preferably curved to conformto-theper forations 4 as shown by Figs. III and ,V. Locking lever F isalsoprovided with a flange ;9 adapted to extend. downwardly. as shown inFig. III and'engage the'depressed middleportion of the gripping lever E,so as to force the abutment flange 16 toward the prongs 3'. Thegrippinglever E is 'provided with a tongue lO'adapted :to be en--gaged-by the extension 9, as shown in Fig. V, sothe lever F can beshifted from the. positions'how'n in Fig. III to the positionshowninlFig. V, with the-result off'movin'g the abutmentfiangeoaway'from the pron s 3. The device is thus unlocked to permlt tongue. servesas means for preventing lateral motion where it will serve as a stop forthe sheets of paper delivered. to the tympamone of these sheets beingindicated by D in Fig. 1. After the prongs have been inserted into thetympan, the locking lever F is moved from the position shown by Fig. Vto the position shown in Fig. HT, thereby firmly gripping the tympanbetween the abutment flange 6 and the prongs 3. The prongs may benotched at 11, and the lower edge of abutment flange 6 will forceportions of the tympan sheet into these notches to secure the device. a

H designates a thin flexible sheet metal tongue located below thelocking lever E and extending through a slot 12 in the abutment flange6, said slot being shown most clearly in Figs. TX and XI. The flexibletongue H. has a front portion inclined upwardly from the abutment flange6 and the rear portion inclined downwardly from said abutment so as tolie between the prongs 3 and engage the bottom face of the grippinglever E. When the parts occupy positions shown by Fig. V, the tonguel lcan be adjusted longitudinally. This tongue serves as a stop forlimiting the upward motion of the edges of the paper sheets engaging theabutment 6. The. sheets are frequently slightly curled at their edgesand when thrown against the abutment 6 they tend to pass over the entiredevice, but the tongue H prevents such displacement of the sheets.

The locking lever 19 has a downturned portion .13 (Figs. HT and IV) infront of the upper portion. of abutment 6, and an end flange 1 linclinedupwardly from said downturned portion. The tongue H prevents the sheetsof paper from entering between the abutment 6 and the downturned portionof the locking lever 13. At the junction of the end flange 14% and thedownturned portion 13, a notch 15 is formed, said notch being open atthe bottom to re ceive the tongue H. When the locking lever F is forcedto its locking position (Fig. TH) it engages the flexible tongue H andslightly bends the same at the abutment 6. j

The tongue H is then located in the slot 15 at the junction of theelements 1.3 and 14: so,

as to prevent lateral displacement of said The locking lever F thereforetion of the tongue H, and it engages said tongue to bend it slightly, asshown in Fig. Ill. To prevent longitudinal displacement of the tonguel-l, it is engaged by the locking lever F, as just pointed out, and aportion of this tongue lies directly between the depressed middleportion of the gripping lever E and the tympan sheet A. The prongs 3 arepressed to provide longitudinal ribs 16 on their top faces, and theseribs lie below portions of the tympan sheet A. so as to elevate the sameat a point below the depressed portion of the gripping lever E. So whenthe gripping lever is forced to its locking position (Fig. III) thetongue H will be gripped between the bottom of this depressed portionand the top of the tympan sheet A.

From the foregoing it will be understood that the tongue H is securedthrough the medium of the means for securing the guide, or gage, to thetympan, and that it is not necessary to provide any additional devicesfor holding the tongue in the position to which it is adjusted. Thistongue can be very easily removed from the device whenever it wouldinterfere with printing near margins of the sheets, and when the tongueis removed, the extended elements 13 and on the locking lever F willtend to prevent the sheets from sliding from the device. However, theseelements 13 and 14 (Fig. III) are not absolutely reliable, for the edgesof said sheets may enter between the abutment 6 and thedownturned'portion 13. When the tongue H is in service, it positivelyprevents the edges of the sheets from entering between the portion 13and abutment 6. V
